Implementation intention formed by making a specific action plan has been proved effective in improving physical activity (PA) and dietary behavior (DB) for the general, healthy population, but there has been no meta-analysis of their effectiveness for patients with chronic conditions. This research aims to analyze several explanatory factors and overall effect of implementation intention on behavioral and health-related outcomes among community-dwelling patients.
We searched CIHNAL (EBSCO), PUBMED, Web of Science, Science Direct, SAGE Online, Springer Link, Taylor & Francis, Scopus, Wiley Online Library, CNKI, and five other databases for eligible studies. Random-effects meta-analysis was conducted to estimate effect sizes of implementation intention on outcomes, including PA, DB, weight, and body mass index. And the eligible studies were assessed by the Cochrane Collaboration's tool for risk of bias assessment. Sensitivity analysis adopted sequential algorithm and the p-curve analysis method.
A total of 54 studies were identified. Significant small effect sizes of the intervention were found for PA [standard mean difference (SMD) 0.24, 95% confidence interval (CI) (0.10, 0.39)] and for the DB outcome [SMD -0.25, 95% CI (-0.34, -0.15)]. In moderation analysis, the intervention was more effective in improving PA for men ( < 0.001), older adults ( = 0.006), and obese/overweight patients with complications ( = 0.048) and when the intervention was delivered by a healthcare provider ( = 0.01).
Implementation intentions are effective in improving PA and DB for community dwelling patients with chronic conditions. The review provides evidence to support the future application of implementation intention intervention. Besides, the findings from this review offer different directions to enhance the effectiveness of this brief and potential intervention in improving patients' PA and DB.

为改善普通健康人群的身体活动（PA）和饮食行为（DB）而制定的具体行动计划所形成的实施意向已被证明是有效的，但对于慢性病患者，尚未对此类计划的效果进行荟萃分析。本研究旨在分析几种解释因素以及实施意向对社区居住患者行为和健康相关结果的总体影响。
我们在 CIHNAL（EBSCO）、PUBMED、Web of Science、Science Direct、SAGE Online、Springer Link、Taylor & Francis、Scopus、Wiley Online Library、CNKI 和其他五个数据库中搜索了符合条件的研究。采用随机效应荟萃分析来估计实施意向对 PA、DB、体重和 BMI 等结局的效果大小。并使用 Cochrane 协作风险偏倚评估工具对合格研究进行评估。敏感性分析采用序贯算法和 p 曲线分析方法。
共确定了 54 项研究。PA 干预的效果存在显著的小效应量[标准均数差（SMD）0.24，95%置信区间（CI）（0.10，0.39）]和 DB 结局的效果[SMD -0.25，95% CI（-0.34，-0.15）]。在调节分析中，干预对男性（<0.001）、老年人（=0.006）、有并发症的肥胖/超重患者（=0.048）和由医疗保健提供者提供的干预（=0.01）更有效。
实施意向对改善慢性病社区患者的 PA 和 DB 是有效的。该综述提供了支持未来应用实施意向干预的证据。此外，本综述的研究结果为增强这种简短且潜在的干预措施在提高患者 PA 和 DB 方面的有效性提供了不同的方向。
